شبكة الالمنيوم، خليط بوليمري، غبار السليكا ، البوليسترالملخص
تم تحضير مادة بوليميرية متراكبة بطريقة القولبة اليدوية. المادة الاساسية تتكون من 90% كسر حجمي من البوليستر مع 10% كسر حجمي من بولي يورثاين.وهذا العمل يقسم على مرحلتين . المرحلة الاولى كانت دراسة تأثير اضافة شبكة من الالمنيوم الى البوليستر بنسب حجمية مختلفة 5% ,10% ,15% و20 %. المرحلة الثانية كانت دراسة تأثير اضافة غبار السليكا (SF) بنسب وزنية مختلفة 1.5% ، 2%الى البوليستر المقوى بالألياف الالمنيوم . أظهرت النتائج زيادة في (مقاومة الانحناء، مقاومة الصدمة، الصلادة والتوصيلية الحرارية) مع زيادة في نسب الالياف المعدنية وعند مزج الالياف المعدنية مع غبار السليكا تتحسن خواص البوليستر. القيمة القصوى لمقاومة الانحناء هي B1 180 MPa عند 20 % حجم شبكة من سبائك الألومنيوم. كانت اعلى قيمة لقوة التأثير هي B1 (9 kJ/m2) عند 20% من شبكة سبائك الالمنيوم. الحد الأقصى لقيمة الصلابة وجد أنها B1 (83) عند %20. الحد الأقصى لقيمة التوصيل الحراري وجد أنها (B1 (0.9 W/m.°C عند 20 %حجم شبكة من سبائك الألومنيوم).
